This article examines predictors of intimacy between husbands and wives. Emphasis is on equality of spouses. A causal model is presented.

This article draws on psychoanalytic theory and a previous study by Whiting (1964) to test the relationship between parent-child sleeping arrangements, particularly the implied social distance of fathers, and the presence of circumcision for males. Circumcision is assumed to be a social correction for mother-oriented personality in sons.

Building on comparative study of the Mormons, Texans, and Zuni in the Rimrock area of Southwestern U.S., the authors cross-cultural test some hypotheses cross-culturally.

This article seeks to examine the distribution and frequency of bride-theft. Tylor's (1889) findings between various forms of marriage by capture and certain other social instituions are confirmed.

This article examines the relationship between polygynous living quarter arrangements and the presence or absence of circumcision and segregation of males at puberty. The amount of contact between the father and son is also examined as a factor.

The significance of the son's insufficient contact with his father during infancy in regard to circumcision and segregation is examined. This article suggests that it is not the long postpartum sexual taboo but the separation of each co-wife that is instrumental in bringing about circumcision and segregation. Expands on Kitahara 1974.

This article presents two evolutionary models that may explain relationships between war and socialization of children: the "environmentally contingent reproductive strategy" (ECRS) model put forward by Draper and Harpending (1982), and a model put forward by Carol and Melvin Ember. Results do not provide support for the hypotheses involving father-infant sleeping proximity derived from the ECRS model. The authors also find some inconsistencies with their own model.

This book examines male and female power in various kinship configurations. Variables for male dominance and female autonomy are associated with various political and social variables, such as political complexity and co-wife jealousy. Several hypotheses are supported.

This study explores ecological reasons that might explain why boys are mostly circumcised in tropical regions, particularly in Africa and the insular Pacific. The author postulates a long causal chain linking: 1) tropical climate to the growing of root and fruit crops; 2) the need to keep babies on mother's milk for as long as possible where the adult diet is lacking in protein; 3) a long post-partum sex taboo as a way to space births; 4) the practice of polygyny (and associated mother-child sleeping) in the face of a long sex taboo; 5) patrilocal residence; and 6) male initiation ceremonies which are believed to result from the combination of mother-child sleeping, the long poast-partum sex taboo and patrilocal residence.

This article investigates determinants of the couvade; the authors reexamine some of their earlier findings and also consider Broude’s (1988) response to their previous studies. Exclusive mother-infant sleeping arrangements, matrilocal residence, and “protest masculinity” (a concept suggested by Broude) were all found to be associated with the couvade. Father-salience in infancy, also suggested by Broude, was only marginally associated.
